SPRING AIR-GUN.

SPECIFICATION forming part of Letters Patent No. 437,491, datedSeptember 30, 1890.

Application filed May 12, 1890. Serial No. 351,504- (No model.)

To all whom it may concern:

Be it known that I, HENRY C. HART, of Detroit, in the county of Vayneand State of Michigan, have invented a new and useful Improvement inSpring Air-Guns, of which the following is a specification.

My invention consists in an improvement in spring air-guns, hereinafterfully described and claimed.

Figure 1 is a partial side elevation, partly in section, of a centralportion of the gun; and Fig. 2 is a vertical central section through theend of the magazine and barrel and breech-block and forward end of thespringchamber.

A represents the stock of the gun, usually made of wood.

B represents two similar castings secured together by the screw J, andserving as a trigger-housing and to connect the springchamber with thestock of the gun, as more fully explained in my former application forpatent.

Y represents the spring-chamber of the gun secured at its forward end toa breech-block W and at its rear end to the housing B. D represents acoil-spring within said springchamber, its rear end resting against anabutment X.

E represents a piston-rod passing through spring D and connected withthe forward end of said spring with an air-compressing piston and at therear end with a washer F.

N represents a lever by which the spring D is compressed.

G represents a rod, one end of which isconnected with said washer F, andin my former application the connecting-rod corresponding to G was shownas bent and connected with the operating-lever. Instead of thatarrangement I have substituted the one herein shown by interposingbetween the connecting-rod G and the lever N avibrating lever I, pivotedat one end on the screw J, and to the other end of said lever theconnecting-rod G is pivoted.

K represents a connecting-rod pivoted at the point L to the centrallever I, and pivoted at its other end at the point M to anoperating-lever N, which is pivoted at the point 0 in a slot cut in thetop of the stock A. By this arrangement I avoid a bend in theconnecting-rod between the piston-rod and the operating-lever andtransmit the power of the lever to the piston-rod more easily and withless loss.

The other part of my invention relates to the carrier-block.

P represents a movable carrier=block moving in an aperture in thebreech=block W, and provided with a spring Q, whose free end is forkedand engages with slots in the carrierbloek P, as shown in my formerapplication, and whose other end is held in a keeper R on the under sideof the spring-chamber.

U represents a false barrel, similar to that in my former application,containing a true barrel T and a magazine S, in which V represents anumber of shot. The rear end of the magazine communicateswith a hole inthe breech-block W, in which the carrierblock P works, and thiscarrier-block is made of such length that, when it is drawn down bypullingdown on the free end of the spring Q, the last shot in themagazine will roll into the aperture in which said carrier-block 'Pmoves and will lie on the upper end of said carrier-block. When thespring Q is released, the carrier-block pushes said shot up ward andlightly pinches the shot between its upper end and the upper surface ofthe true barrel, as shown in Fig. 2, whereby said shot is prevented fromrolling out of the gun by gravity or by shaking, but yet is left free tobe discharged by a blast of compressed air from the spring-chamber Y.

VVhatI claim as my invention, and desire to secure by Letters Patent,is-

In a spring air-gun, the combination, withan operating-spring and itspiston-rod, of an operating-lever pivotally secured to the stock, anintermediate lever pivoted to the gun, and two connecting-rodsconnecting said intermediate levers respectively with the piston-rod andthe operating-lever, substantially as shown and described.

2. In a spring air-gun, the combination, with a true barrel and amagazine, of a movable carrier-block and an actuatingspring,

whereby said carrier-block is adapted to transfer a ball from themagazine to the barrel and pinches the shot between its upperiend andthe upper surface of the true barrel, sub stantially as shown anddescribed. I

HENRY C. HART.
